Incorporating the latest in fluidisation and combustion technologies, Arcon supplies Fluidbed Furnaces that are at the technological edge of furnace design.
 

HOW IT WORKS


In the fluidbed multiple strands of continuous steel wire are heated by passing horizontally through a bed of fluidised aluminum oxide particles. Air and gas are introduced in the bottom of the bed through a double distribution network. Combustion occurs within the bed, providing rapid heat-transfer to the sand particles and wires. The bed is contained between corrugated retort walls of high nickel alloy steel that are specially designed to withstand the stresses of thermal cycling.

Layers of ceramic fibre material are used to insulate the outside wall of the Fluidbed, providing a low skin temperature and efficient operation. The furnace frame is constructed of welded structural steel sections and heavy gauge panels. Each fluidbed is custom-designed to suit production requirements.

 

ADVANTAGES


Arcon supplies fluidbeds that are designed for high wire speeds with optimum air and gas flow rates. The development of a labyrinth seal threading slot eliminates the maintenance and heat loss costs associated with "curtain" style fluidbed designs.

The new injected fuel system permits the use of a variety of gasses, while eliminating flashback problems. Even fluidisation is assured through a specially designed air distribution manifold that replaces the costly and maintenance-prone tiles of older designs.
